A report on the Welsh-language BBC Cymru site reports research by Ann Dowker and others at Oxford University into maths skills among children, which may show that Welsh children find basic mathematical concepts easier due to the Welsh counting system. The traditional Welsh counting system is vigesimal, but another system, using forms like 'un deg tri' (one ten three) for 13, 'dau ddeg tri' (two ten three) for 23, is in widespread use.
The report (in Welsh) can be read below. I've been unable to find a link to an English language version.
